Hey, firstly I must say I think its great game. Very challenging, especially C2 for me!
The annoying thing is that a bug has now wrecked my progress at 67%. I had just emerged into the leftmost portal on D2. (I think you come there from B1). I have 8 powerups and when coming out that portal the commander said "great you can get to E2 from here" (or something like that!) but I couldn't see how that was possible so went back into the portal. It then ended up placing me outside the maze on screen B2. And each time I load it thats where I start. Such a shame because I was looking forward to finishing.
I'll start again I guess but if you can get that fixed it would be much appreciated!
Ps. Keep up the good word. 10 stars :)
